Every kill you make and mission you complete funnels back into an incredibly
robust unlock system, granting persistent currency on a range of planes with different stats, an array of weapons from missiles to bombs, Stand - Off Dispensers and lasers, plus upgrade parts to tune your performance.
Strangely, there's a fairly
robust character customization
system that offers
unlocks through a level - based character progression and I find it odd that more time was put into cosmetic nonsense instead of gameplay content.
